Detailed Description
The invention is further described below in connection with embodiments. The following embodiments are only for more clearly illustrating the technical aspects of the present invention, and should not be used to limit the scope of the present invention.
The invention provides a taper contact connector, referring to fig. 1 and 2, which comprises a plug 20 and a socket 10 which are plugged. Referring to fig. 3 and 5, the plug includes a plug pin 21, a plug insulator 22, and a plug housing 23; the plug insulator 22 is sleeved on the plug pin 21, and the plug shell 23 is sleeved on the plug insulator 22; the front end of the bolt 21 is in a truncated cone shape or a cone shape, and the tail end of the bolt is connected with the second cable. Referring to fig. 4 and 5, the socket includes a socket 11, a socket insulator 12, a socket housing 13, and an elastic member; the shape of the front end of the inner cavity of the plug bush 11 is matched with that of the front end of the plug pin, and the tail end of the plug bush 11 is connected with a first cable; the outer side surface of the plug bush 11 is provided with a second limiting step 17, the second limiting step 17 is positioned at the front end or the front part of the plug bush 11, the inner side of the socket insulator 12 is provided with a first limiting step 16, the plug bush 11 passes through the first limiting step 16 to be in sliding connection with the socket insulator 12, and the elastic piece is positioned in a first cavity formed by the socket insulator, the first limiting step, the plug bush and the second limiting step; the socket housing 13 is fitted over the socket insulator 12.
When the plug is inserted into the socket, the plug pin is inserted into the plug bush and pushes the plug bush to move along the axis of the plug bush, and the plug pin and the plug bush are pressed tightly under the action of the spring, so that reliable contact force is generated. Meanwhile, the contact surface between the bolt and the plug bush is large, so that the contact resistance can be effectively reduced, and the round table type or conical bolt is stable and is not easy to damage. The invention does not limit the forms of the plug shell and the plug sleeve shell, and the existing plug shell and plug sleeve shell are adopted.
In an alternative embodiment of the present invention, referring to fig. 3 and 4, the plug further includes a second retainer 24; the inner side surface of the plug insulator 22 is provided with a limit step III 25; the tail end of the bolt 21 is provided with a limit step IV 26, and the middle part is provided with a check ring II mounting groove; the plug passes through the third limit step 25 and is fixed in the plug insulator 22 by the second retainer 24.
In an alternative embodiment of the invention, see fig. 4, the front end of the bolt 21 is truncated cone shaped.
In an alternative embodiment of the invention, referring to fig. 3, the socket further comprises a retainer ring one 15. The second limiting step 17 is positioned at the front end of the plug bush 11, a first check ring mounting groove is formed in the outer side face of the middle of the plug bush 11, the first check ring 15 is mounted on the first check ring mounting groove, and the first check ring 15 and the second limiting step 17 are respectively positioned at two sides of the first limiting step 16. The first check ring is C-shaped and is made of stainless steel.
In an alternative embodiment of the invention, see fig. 4, the resilient member is a spring 14. When the spring is used, the proper spring can be selected according to the requirement, so that the pressing force of the spring can ensure that the plug bush and the plug pin keep in contact effectively under the condition of vibration or impact.
In an alternative embodiment of the invention, the plug housing comprises a plug housing inner layer and a plug housing outer layer; the inner layer of the plug shell is fixedly connected with the outer layer of the plug shell; and a cavity III between the inner layer of the plug housing and the outer layer of the plug housing is used for plugging the socket housing.
